INTRODUCTION
Thank you for buying this Synq® product.
This document is only a brief introduction and mainly describes the OSC Protocol instructions supported by
the Synq® DBI and DBT Dante network audio bridges.
This is NOT a full course on OSC, the internet is already full of very useful information about OSC.
To take full advantage of all possibilities of the Synq® DBI and DBT Dante network audio bridges, please
download and read the separate operating instructions very carefully. Also the webpages of the DBI and
DBT have an intuitive help function that explains all functions easily.
REVISION HISTORY
This is a work in progress, so check the Synq website regularly for new updates!

WHAT IS OSC ?
Open Sound/System Control (OSC) was created as a successor to the MIDI control protocol. It enables
communication between computer software, sound synths and other multimedia devices that support OSC.
Its advantages over MIDI include:
• An open-ended and dynamic URL-style symbolic naming scheme
• Symbolic and high-resolution numeric argument data
• Pattern matching language to specify multiple recipients of a single message
• High resolution time tags and “bundles” of messages whose effects must occur simultaneously.
The protocol is also not bound by specific hardware (i.e. MIDI cables and ports) and can be transferred
across any network connection, even remotely via the internet.
This makes OSC much more powerful than MIDI, but due to its open-ended specification, both the OSC
client (sends OSC requests) and the OSC server (receives and executes requests) must be separately
configured, unlike MIDI which is essentially “Plug & Play”.

API
An API is a set of instructions (often in the form of URLs), written by the developer, to give other developers
a common standard method for writing software that connects different systems or components of a system,
without having to understand all the complexity. In short: an API reduces the complexity and greatly
increases the speed of programming.
Below you can find the current set of URLs and descriptions for each function that can be controlled on the
Synq® DBI and DBT units, using OSC.
If a URL is sent without a parameter value, the command will be interpreted as a "get": the device will return
the current state.
Each URL ends with "/<device_name>": this allows multiple devices on a network to be accessed via
broadcasting.
Each command can also work with the type as "float".
